Application fiIed Ma-y 14,

To all whom it may concern:

Be it known that I, YANoEY QUITMAN CALDWELL, a citizen of the United States, and a resident of Paris, in the county of Henry and State of Tennessee, have invented certain new and useful Improvements in Swi ch Stands, of which the following is a specification.

This invention relates to an improvement in switch stands, and more particularly to an improvement in switch handles or switch levers adapted to be organized with switch stands. I 7 The object of the invention is to provide an improved switch handle or switch lever which is of simple and durable construction, reliable andeasy in operation and wherein the locking means although adapted for general use is embodied or incorporated in the structure of the'switch handle in such a manner as to be protected from the weather and from manipulation by unauthorized persons and yet at the same time susceptible of operation by authorized persons while serving to securely'hold the mechanism of the switch stand in adjusted position.

' Other objects and advantages or the in: vention reside in certain novel features of the construction, combination and arrangeinent of parts. which will be hereinafter more fully .described and particularly pointed out in the appended claims, reference being had to the accompanying drawings forming part of this specification, and V in which:

Figure 1 is a perspective view, showing the preferred embodiment of the invention organized with the switch stand;

Figure 2 is. a group view in perspective, showing the parts ofthe switch handle prior to assembly;

'Figure 3 isa view, partly in vertical sec- .tion' and partly in elevation, showing the switch handle applied to the switch stand; and

' Figure 4 is a fragmentary view in elevation, showing the switch-handle applied to the switch stand.

Referring to the drawings, the numeral 10 designates generally the switch stand which preferably comprises a shell like or hollow housing 11, a portion of which is broken away in order to more fully illustrate the invention. The lower end of this 1923. Serial No. 638,994.

carries a target or other signalling means 18. V

A bracket orcarrier 20 is loosely mounted on theshaft 15 above "the head 14 and the outer end of the carrier is bifurcated to revide' spaced arms 21 to-which? the switch I handle orlever, designated generally at22, is pivotally connected, as at 23.'

The switch handle or lever which constitutes the present invention includes a body or stock 23, a handle portion 24 and aiportion 25 by which the lever is pivotally, mounted and by which it is operatively connected with the operating or actuating means for the switch. The handle portion i 2 1 tapers toward its outer end whereby it may be more convenientlyg p 1 portion :25 is reduced in width'as clearly shown in Figure 2 in order to better adapt it to its purposes as will presentlyappear.

In the'body portion or stock 23 a chamber 26 is provided and opens to the outer or,

upper face of the switch lever. A trans verse slot 27' is provided in the body portion or stock 23 and communicates with the side of the body portion. slot 27 which intersects the chamber is disposed centrally and toward the lower end 1 thereof. In the'.chamber26 a lockdesignated generally at 28 is fitted. 'This lock28 includes a casing 29 h avingan opening 30 adapted to coincide or registerwith the slot 27. The lock also includes an arcuatebolt- 31 adapted to be. extended or projected across the opening 30' and also across the slot 27. Key operated means, designated generally 211132 is providedfor controlling the bolt 31 This lock 28 is complete in it- I self and is adapted for: general use and preferably is the precise lock or the type of lock described and shown inmy pending application filed March 14, 1923, Serial No. 625,112. The lock 28 is enclosed and pro tected in the cavityor'chamber 26 bymeans of a cover plate 35 having pivot ears.36 at its upper end adapted tobe fitted in the recesses 37 provided therefor in the portion chamber 26 and extends through theunder- Preferably this means of abolt or screw 39 having threaded of the switch lever and to be'pivotally between the recesses 37. The lower end of the cover plate 15 secured in any suitable manner to the stock or body portion 23 of the handle and preferably is so secured by connection with the cover plate and the f bore provided in he stock or body. In the lower portion'oi the cover plate 89 a slot 40 is provided and in the assembly registers with the opening 30 of the lock and the slot 3? of the stock or body portion or the hendle and through these alined slots and openings 27, 30 and 40 staples 42 of the switch stand are adaptedfto extend in certain posi- The cover plate 35 hey openlng aimed with the key operated means of thelock and provided with suitable closure 42.-
